Multiquip 1971885003 DC Reactor GLW-180H - OEM Replacement Part for Welder-Generator

The DC Reactor GLW-180H regulates and stabilizes direct current output in Multiquip welder-generators, ensuring consistent arc performance across SMAW, FCAW, GMAW, and GTAW welding applications. This critical component protects the welding circuit by smoothing current fluctuations and preventing voltage spikes that can compromise weld quality or damage electrical components.

Engineered for the GAW180HE series welder-generator, this DC reactor supports maximum current output of 180 amps and rated current of 170 amps at 50% duty cycle. The reactor works in conjunction with the welder's polarity system, maintaining stable performance whether operating in straight polarity (electrode negative) or reverse polarity (electrode positive) configurations. When the reactor fails, symptoms typically include erratic arc behavior, inconsistent amperage output, difficulty maintaining arc stability, or premature protection device shutdowns.

This reactor is essential for maintaining the GAW180HE's 4.56 kW rated output and 26.8V DC arc voltage specifications across the full 30-180 amp current range with applicable electrode sizes from 3/32" to 5/32".
